Replaying archived Amazon EventBridge events - Amazon EventBridge
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Replaying archived Amazon EventBridge events

After you create an archive, you can then replay events from the archive. For example, if you update an application with additional functionality, you can replay historical events to ensure that the events are reprocessed to keep the application consistent. You can also use an archive to replay events for new functionality. When you replay events, you can specify which archive to replay events from, the start and end time for the event to replay, the event bus, or one or more rules to replay the events to.

Events aren't necessarily replayed in the same order that they were added to the archive. A replay processes events to replay based on the time in the event, and replays them on one minute intervals. If you specify an event start time and an event end time that covers a 20 minute time range, the events are replayed from the first minute of that 20 minute range first. Then the events from the second minute are replayed. You can use the DescribeReplay operation of the EventBridge API to determine the progress of a replay. EventLastReplayedTime returns the time stamp of the last event replayed.

Events are replayed based on, but separate from, the PutEvents transactions per second limit for the Amazon account. You can request an increase to the limit for PutEvents. For more information, see Amazon EventBridge Quotas.

Note

You can have a maximum of 10 active concurrent replays per account per Amazon Region.
